麦克斯韦等离子体中横向电磁场产生纵向电流

Generation of longitudinal electric current by transversal electromagnetic field in Maxwellian plasmas

A. V. Latyshev, A. A. Yushkanov

摘要:

分析了横向电磁场与麦克斯韦无碰撞经典等离子体和量子等离子体的非线性相互作用。推导了麦克斯韦无碰撞经典等离子体和量子等离子体中电流的计算公式。它已经出现,非线性帐户导致发生的纵向电流沿波矢量的方向。该第二电流与在经典线性分析中接收的已知横向电流正交。对经典麦克斯韦等离子体和费米-狄拉克等离子体(具有任意电子气体退化程度的等离子体)的电流密度进行了图解比较。对经典麦克斯韦等离子体和量子麦克斯韦等离子体的电流密度进行了图解比较。比较了在不同的电磁场无量纲振荡频率下,量子麦克斯韦等离子体的电流密度与无量纲波数的关系。

英文摘要:

The analysis of nonlinear interaction of transversal electromagnetic field with Maxwellian collisionless classical and quntum plasmas is carried out. Formulas for calculation electric current in Maxwellian collisionless classical and quntum plasmas are deduced. It has appeared, that the nonlinearity account leads to occurrence of the longitudinal electric current directed along a wave vector. This second current is orthogonal to the known transversal current, received at the classical linear analysis. Graphic comparison of density of electric current for classical Maxwellian plasmas and Fermi---Dirac plasmas (plasmas with any degree of degeneration of electronic gas) is carried out. Graphic comparison of density of electric current for classical and quantum Maxwellian plasmas is carried out. Also comparison of dependence of density of electric current of quantum Maxwellian plasmas from dimensionless wave number at various values of dimensionless frequency of oscillations of electromagnetic field is carried out.
